Abstract

The invention discloses a washing machine drain valve tractor. The washing machine drain valve tractor comprises a motor, a speed reducing mechanism and an electric connecting mechanism; the speed reducing mechanism comprises a first mounting plate; a one-way wheel and a knob gear are arranged on the first mounting plate; an output gear meshed with the one-way wheel is arranged on an output shaftof the motor; a plurality of intermediate transmission gears which are connected in sequence are connected between the one-way wheel and the knob gear, and the knob gear is connected with a drainage knob; the electric connection mechanism comprises a second mounting plate; a fixed contact piece and a movable contact piece opposite to the fixed contact piece are arranged on the second mounting plate; and a cam is arranged on the drainage knob, and the cam is located on one side of the movable contact piece. The motor can be accurately controlled to stop, and smooth work of the drain valve is guaranteed.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a puller for a drain valve of a washing machine. Background technique [0002] The drain valve is an important part on your washing machine. Existing drain valves generally include a valve body, a sealing component, and a tractor, and the movement of the sealing component is driven by the tractor, thereby realizing the opening and closing of the drain valve. [0003] At present, the general pattern of washing machine drainage is: the tractor rotates→opens the drain valve→keeps it open→drains water→closes the drain valve. [0004] The existing tractor includes a motor and a drain knob that rotates under the drive of the motor. A protruding shaft is arranged eccentrically on the drain knob, and a connecting rod is connected to the protruding shaft. One end of the connecting rod is connected with a sealing member, and the motor drives the drain knob to rotate. When the dr...
